rollinggo-searchflight-skill

Flight search and pricing via the RollingGo Flight MCP. Use when the user wants to search flights by origin, destination, date, passenger count, cabin class, city/airport code, or compare real-time flight options and prices. Trigger phrases — "search flights", "find flights", "flight price", "cheap flights", "flight comparison", "机票", "查航班", "查机票", "航班价格", "rollinggo".

RollingGo Flight MCP

When to Use

✅ Use this skill when:

• Flight Search: User wants to find flights between two cities or airports on a specific date.
• Price Comparison: User wants to compare flight prices, departure times, arrival times, direct/transit routes, or airline options.
• City & Airport Resolution: User provides natural language city/airport names and needs them converted into available city or airport codes.
• One-way / Round-trip Planning: User asks for one-way or round-trip flight options with passenger count and cabin preference.
• Flight Option Evaluation: User wants a short list of recommended flights based on price, timing, directness, and supplier score.

❌ Don't use this skill when:

• User asks about hotels, trains, car rentals, transfers, travel visas, attractions, or itinerary planning without a flight-search need.
• User asks to issue tickets, pay, cancel, refund, change flights, manage orders, confirm baggage allowance, or guarantee fare rules. Current documented MCP capability is flight search only.

API Key

Runtime

This skill uses a remote MCP server (streamable_http), not a local CLI runtime. The MCP server is registered automatically by the skill host — no manual configuration or local install is needed.

Load references/rollinggo-mcp.md and keep it for the session.

No API key is required for the public endpoint.

Version Freshness

The remote MCP endpoint is the source of truth. Do not invent local package versions or CLI commands.

Before making claims about newly added tools or booking/payment capabilities, check the latest MCP documentation or the live MCP tool list.

Primary Workflow

Run these steps in order unless the user is already at a later step.

1. Clarify required info: origin, destination, departure date, one-way or round-trip. Optional (use defaults if not specified): return date (required only for round-trip), adult count (default 1), child count (default 0), cabin class (default ECONOMY), airport preference (city-level vs specific airport).
2. If origin or destination is a natural language city/airport name → run searchAirports first.
3. Prefer cityCode for broad city-level searches and airportCode when the user explicitly names a specific airport.
4. Run searchFlights with the resolved codes and passenger/cabin/date parameters.
5. Parse flightInformationList and compare options by price, time, directness, duration, and fromSmartValueScore (higher = better value).
6. If results are weak or empty → loosen filters and retry (see Filter Loosening).
7. Present 3–5 useful options and remind the user that price and inventory are real-time and subject to final confirmation.

MCP Tools Quick Reference

searchAirports — resolve city or airport names to codes

json

{ "keyword": "杭州" }

searchFlights — search available flights (one-way example)

json

{
  "adultNumber": 1,
  "childNumber": 0,
  "cabinGrade": "ECONOMY",
  "fromCity": "HGH",
  "toCity": "CTU",
  "fromDate": "2026-05-01",
  "tripType": "ONE_WAY"
}

Round-trip: add "retDate": "YYYY-MM-DD" and set "tripType": "ROUND_TRIP". Specific airport: replace fromCity/toCity with fromAirport/toAirport.

Key Rules

• adultNumber and childNumber are required. Use childNumber: 0 when there are no children.
• cabinGrade must be one of: ECONOMY, PREMIUM_ECONOMY, BUSINESS, FIRST.
• tripType must be one of: ONE_WAY, ROUND_TRIP.
• fromDate and retDate must use YYYY-MM-DD.
• retDate is required when tripType=ROUND_TRIP and must be later than fromDate.
• For origin, use either fromCity or fromAirport (not both).
• For destination, use either toCity or toAirport (not both).
• If the user only says a city such as "上海" or "成都", prefer fromCity / toCity to cover multiple airports.
• If the user says a specific airport such as "虹桥", "浦东", "天府", or "萧山", prefer fromAirport / toAirport.
• Default cabin class may be ECONOMY when the user does not specify.
• Default passenger count may be 1 adult and 0 children when the user does not specify.
• Do not guess missing travel dates. Ask a brief follow-up unless the date is explicitly recoverable from the user's wording.

Output

MCP response structure:

• message: human-readable status string (e.g. "航班搜索成功")
• flightInformationList: array of flight options

When presenting flights, include for each option:

• total adult price and currency
• child price if children are included
• flight number
• departure and arrival time
• departure and arrival airport codes
• duration in minutes (convert to h/m for display)
• direct / transfer / stop city information (stopCities field; empty string means direct)
• airline or validating carrier code (validatingCarrier)
• fromSmartValueScore as a tiebreaker (0–100, higher = better value)
• short recommendation reason

Always add a note that flight prices and inventory can change in real time and final availability should be rechecked before booking.

Filter Loosening (when no results)

Try in order: switch specific airport code to city code → try nearby airport/city matches from searchAirports → broaden cabin preference to ECONOMY only if user allows → ask whether the user can change date or time window.

If results exist but quality is low → sort by fromSmartValueScore descending before presenting.

Boundary Notes

Current documented MCP capability covers airport search and flight search. Do not claim the skill can complete payment, issue tickets, cancel/refund/change orders, manage bookings, or verify baggage rules unless a corresponding tool is added later.
